Ahh. There's code to take care of this case. Each disk driver (sd, wd, cd,
ccd, vnd, etc.) has a XXgetdefaultlabel routine which will make a default
label. For drives where we can detect the size (scsi, ata, for instance),
this routine will fill in a struct disklabel with a whole-disk partition
that takes up the whole disk. For ports other than i386 & other
MBR-derived ones, that's partition c.

So there will always be a c partition. :-)

Take care,
